(R001)

System connections

You must install a host bus adapter or host channel adapter in the host system.

Installing a host bus adapter or host channel adapter in the host
system

Host bus adapters (HBAs) provide an interface from the host system’s PCI bus to Fibre Channel-attached
devices. Host channel adapters (HCAs) provide an interface from the server’s PCI bus to InfiniBand
devices.

IBM FlashSystem 710 User ’s Guide 3

Ensure that the adapter that you select for use with the storage system provides a driver for the
operating system version that you are using.

Note: In subsequent sections, the term HBA is used to represent HCA or HBA interchangeably.

Before you install the HBA, consult your server documentation to determine which one of its PCI slots is
on the fastest and least congested PCI bus. Follow the instructions that are provided with the HBA to
install the card and driver. Obtain the latest drivers and firmware for the HBA. Updated drivers might
include new functions, improved performance, and minor bug fixes.

The speed of the server and network interface ultimately determine the storage system's capabilities.
Some components that can affect the maximum performance of the storage system include FC or
InfiniBand interfaces, host bus adapters, PCI buses, and server processor resources.

Fibre Channel interface bandwidth

Your storage system supports Fibre Channel (FC) communication speeds of 2 Gbps, 4 Gbps, or 8 Gbps.

Accounting for encoding and overhead, the maximum 8 Gbps transfer rate allows data to be transmitted
to the system at a half duplex rate of approximately 800 MBps. Fibre Channel interfaces have separate
read and write connections that allow a maximum data rate of twice the half-duplex rate. To sustain the
maximum full duplex rate, the data usage pattern of the system must be 50% read and 50% write. This
requirement is because of the individual half duplex limits. To find the maximum for other data usage
patterns, use the following formula (given an 8 Gb HBA):

[(smaller usage percentage/larger percentage) × 800 MBps] + 800 MBps

For example, to calculate a data usage pattern with 66% reads and 33% writes,

[(33/66) × 800] + 800 = 1200 MBps

Many applications require storage bandwidth that exceeds what a single FC connection can provide. To
accommodate this situation, up to 4 FC ports are available per system, each of which can supply the
bandwidth described here. Using multiple FC connections requires one of the following solutions:
multipathing software to a single logical unit, using software to stripe across multiple logical units,
accessing multiple logical units concurrently, or connecting multiple servers to the storage system.

Host bus adapter settings

You can modify some host bus adapter (HBA) settings to increase performance.

For information specific to your HBA, consult the HBA documentation. Many settings are intended to
increase the performance of slow storage devices and are not applicable to this high performance system.

In particular, it is always advisable to check the frame size. The amount of overhead for each Fibre
Channel frame is fixed, so larger frames have lower overhead. Set the frame size to the maximum setting,
generally 2048 bytes. For InfiniBand devices, also set the frame size to the maximum setting, generally
4096 bytes.

PCI bus selection and performance

High-bandwidth host bus adapter (HBA) traffic can quickly inundate slower PCI buses. When a PCI bus
reaches its limit, you can do little to improve performance.

Many servers, however, provide different PCI buses with different speeds, and placing the HBA on a
faster PCI bus can improve performance. When you install an 8 Gb, 2-port HBA in the server, allocate at
least an entire PCI-X bus or a PCI Express (PCIe) slot.

4 IBM FlashSystem 710: User's Guide

Processor performance factors

At a certain point, processor performance can limit data transfer rates. Determine whether the server’s
processor resources are the limiting factor in performance while you benchmark the storage system as a
raw physical device.

Otherwise, an improperly tuned file system or application can make the processor seem to be the limiting
factor when it is not. Complete raw device testing after you set up any multipathing.

There are a few ways to decrease processor usage without increasing processor resources. Certain data
usage patterns can be processor-intensive and fully use the processor. These usually involve small
transfer sizes. When possible, increasing the average transfer size decreases processor usage and offers
better performance.

Another way to decrease processor usage is by enabling interrupt coalescing. Interrupt coalescing is an
HBA-dependent function that decreases processor usage at the expense of latency. This function delays
the calling of the HBA transfer interrupt until several transfers are ready. However, in general, do not
enable interrupt coalescing because the storage system performance benefits from low latency. For more
information, see your HBA documentation.

Connecting the Fibre Channel or InfiniBand ports

Connect the Fibre Channel (FC) ports on the storage system to your server or to an FC switch. If your
storage system has InfiniBand ports, connect them to an InfiniBand switch or host channel adapter (HCA)
in your server.

The following figure shows the port layout for the storage system. Each controller has two FC ports: A
and B, on the left and right respectively. The FC ports on the system can connect to Point-to-Point
(N-Port), Arbitrated Loop (NL-port), or Switched Fabric (F-Port) topologies at 2 Gb, 4 Gb, or 8 Gb speeds.

Figure 1. Fibre Channel or InfiniBand port locations

Although Figure 1 shows FC controller cards, an InfiniBand controller card can occupy either of the same
slots as the FC controller cards. The InfiniBand controller card has two x4 InfiniBand ports: A and B, on
the top and bottom respectively. The InfiniBand ports can connect to Quad Data Rate (QDR), Double
Data Rate (DDR), or Single Data Rate (SDR) HCAs. This connection uses the Small Computer System
Interface (SCSI) remote direct memory access (RDMA) Protocol (SRP).

v On an FC controller card, the FC port LED is green if the speed is set to 8 Gb. If the speed is set to 4

Gb, the LED for the FC port is amber.

v On an InfiniBand controller card, the port LED is green when the link is established.

Connecting the system to a management network

Your system includes a Gigabit Ethernet management controller port (MCP) connection for remote
management over a network.

You use this connection to configure the system's storage and management functions.

IBM FlashSystem 710 User ’s Guide 5

Figure 2. Ethernet management port location

Connect the Ethernet MCP to the network.

Connecting power to the system

Although the system operates when only one power supply is connected, this set up is not
recommended.

Using the ac power cords that are provided, connect each power supply to a power source. As a best
practice, connect each of the power cords to separate circuits.

menu instead of reselecting the same IP configuration.

Additional system management options

After you set up the basic system management options, you can use these additional functions. The
functions include connecting by using Telnet and Secure Shell (SSH), monitoring your system with
Simple Network Management Protocol (SNMP), and other advanced options.

Connecting by using Telnet and SSH

When you configure the Ethernet port on the storage system, you can remotely monitor the system by
using a Telnet or SSH session.

Set your terminal settings to VT100 mode.

Connecting by using the web management interface

The storage system is equipped with a browser-enabled tool to facilitate system monitoring, management,
and configuration.

IBM FlashSystem 710 User ’s Guide 11

This monitoring application is based on Java. A separate document, the Web Interface Guide, provides
expanded information about this interface.

Monitoring by using SNMP

Your storage system supports the Simple Network Management Protocol (SNMP), which is the dominant
network management protocol.

The industry accepts this protocol because of its relative simplicity. SNMP standards provide a
framework for the definition of management information along with a protocol for the exchange of that
information. The storage system is compatible with SNMP v2c.

The SNMP model contains managers and agents. A manager is a software module responsible for
managing the configuration on behalf of the network management application users. Agents are devices,
such as your storage system, which is responsible for maintaining local management information and
delivering that information to a manager by SNMP. Both the manager and the agent can initiate
management information exchanges.

Managers can access statistical information from the storage system through its management information
base (MIB). For more information, see the SNMP Guide.

The Lightweight Directory Access Protocol (LDAP) function provides central authentication of login
credentials in addition to any local users.

Note: Users that are authenticated on the LDAP server are granted user-level permissions.

Before you use this function, you must first configure the LDAP settings to match the server.

To configure the LDAP settings, select the User's node under Management in the system tree. The
configuration wizard includes the following settings:

Host This setting is the LDAP server. It must be resolvable without using LDAP. Multiple hosts might

be specified, each separated by a space.

Base DN

This setting is the distinguished name (DN) of the search base.

Port (Optional) This setting is the port that is used to connect to the LDAP server. The default setting

uses port 389 for TLS or no encryption, or port 636 for SSL encryption. If you use a different port,
make sure to specify it in this field.

Bind DN

(Optional) This setting is the distinguished name that is used for binding to the LDAP server. If
left in the default setting, the storage system tries to bind anonymously.

Bind Password

(Optional) This setting is the password that the LDAP server uses to authenticate the “Bind DN”
when the storage system tries to bind.

14 IBM FlashSystem 710: User's Guide

Storage modes

Your storage system is configured with a specific storage mode.

Each mode is tailored to a use case for a high capacity solid-state disk.

Attention: You cannot switch between storage modes, as this is a destructive action and causes data
loss.

Maximum capacity

Maximum capacity mode is the most flexible and is useful in an environment where the entire capacity of
the unit is needed.

The maximum capacity storage mode is used to create logical units and assign access policies as needed.
This mode is well-suited for deployments where the storage system is mirrored or preferred read
mirrored with other storage. (In a preferred read mirror implementation, data is read from the storage
with the lowest latency (the flashcards in the storage system).

Data acquisition

This specialized storage mode creates one logical unit and assigns access policies to all interface ports.

This data acquisition mode is used to present the entire storage space to all connected devices.

JBOF

The Just a Bunch of Flash (JBOF) storage mode automatically creates one logical unit for each flashcard
present in the system.

The administrator can then assign access policies as needed. JBOF mode is useful in an environment
where a host-based software RAID can be created to increase redundancy across the flashcards.

Active spare

The active spare storage mode automatically uses the last flashcard in the unit as a spare. This function
provides another level of redundancy when a flashcard fails, in an environment where some of the
storage capacity can be sacrificed for this additional data redundancy.

With the active spare storage mode, if a card experiences a recoverable failure (that is, a flash chip fails),
the data is migrated off the failed card and onto a designated spare. The failed card is later replaced and
the newly installed card becomes the new active spare storage mode. Note that the flashcards are not
hot-swappable. In this storage mode, there are still a few components that are not protected by active
spare storage mode, so there is a risk of an unrecoverable component failure. If a deployment requires no
single point of failure, mirrored storage systems that use the maximum capacity storage mode is the
preferred solution.

Attention: The failed card must be replaced immediately after the data replication is complete.

Creating logical units

The most common management activity on the storage system is logical unit creation.

About this task

Basic logical unit creation activities are covered here. For more detail, see the Web Interface Guide.

Important: For specific operating system and application optimizations for logical units, see the storage
system Integration Guide.

To create a logical unit, complete the following steps:

IBM FlashSystem 710 User ’s Guide 15

Procedure

1. In the web interface system tree, right-click the Logical Units tree node and select Create. The logical
unit creation wizard opens.

2. After you read the overview, click the Next button to set the logical unit parameters.

3. The parameters available for the logical unit follow.

Name This setting is a user-defined name for the logical unit to make it easily identifiable.

Number

This setting is the logical unit number (LUN) that is presented to the host.

Size This setting is the size of the logical unit.

Device ID

This setting is an OpenVMS specific identifier.

Sector Size

This setting is the sector size of the logical unit.

Offset This setting sets the logical unit starting alignment to offset.

Report corrected media errors to the SCSI host

This setting controls whether any internal corrected errors are reported over the SCSI layer to
the host. For most environments, enable this setting.

Report uncorrected media errors to the SCSI host

This setting controls whether any internal uncorrected errors are reported over the SCSI layer
to the host. For most environments, enable this setting.

Enable ACA Support

This setting enables Auto Contingent Allegiance (ACA) support for the logical unit. Some host
systems, such as systems that are running the AIX
run multiple concurrent commands. After this option is changed, all interface ports that have
access to the logical unit must be reset.

4. After you set the appropriate values, click Next. A final pane confirms the values. After you click
Finish, the logical unit is created.

®

operating system, require this setting to

Results

For the logical unit to be used, you must define an access policy.

Logical unit access policies

You can use the web interface to create access lists for individual Fibre Channel or InfiniBand ports.

This access list allows the administrator to specify which ports are allowed to communicate with each
logical unit.

New logical units are displayed with a warning state that notifies the administrator that a logical unit
was created. The logical units are not presented to any hosts until an access policy is defined.

Adding an access policy to a logical unit

To make logical units accessible to connected servers, you must first link the logical unit to the storage
system Fibre Channel or InfiniBand ports

About this task

access policies underneath. The tree titled Assigned shows the policies currently in use for each port
in the system. If there are potential conflicts between policies that are assigned and policies that are
available, the conflicting available policies are disabled in the Available tree. If the system detects a
host server that is connected to the controller port for the access policy, the policy node’s connector
icon includes a plus sign.

a. To add an Access Policy, select the wanted policy node from the Available tree. When it is

highlighted, the >> button becomes enabled. Clicking this button moves the policy from the
Available tree to the Assigned tree. When a new policy is added to the Assigned tree, its text
color is green.

b. To remove an Access Policy, select the wanted policy node from the Assigned tree and click the

<< button. The policy is removed from the Assigned tree and added to the Available tree. When

an in-use policy is deleted from the Assigned tree, its text color is red in the Available tree. Policy
changes are not committed until the next step in the wizard.

5. When you finish making policy changes, click Next to continue to the modifications review page.

6. If policy modifications are only policy additions, click the Confirm check box and click Finish to exit

the wizard and commit the policy changes. If there are policy removals, you are required to enter the
admin login password to finish the wizard.

Logical unit masking

The logical unit (LU) masking feature assigns access policies to a LU on the storage system, thus
restricting access to specific host servers through a controller port.

About this task

This feature is opposed to Open Access where the LU is accessible to all hosts connected to the port.

When the LU masking feature is installed, access to specific hosts can be created through the web
management interface’s Access Policy wizard. With LU masking available, the wizard shows the
worldwide port names (WWPNs) of connected hosts in its Available policy tree. The wizard also
supports the ability to create host ID aliases. You can use a host ID alias to associate a meaningful text
name with a host’s WWPN.
